Casio FX 83 ES Calculator

Product Information

Function Calculations This section explains how to use the calculator’s built-in functions. The functions available to you depends on the calculation mode you are in. The explanations in this section are mainly about the functions that are available in all calculation modes. All of the examples in this section show operation in the COMP Mode (N1). • Certain function calculations may take some time to display calculation results. Switching between Fraction and Decimal Format f • The format of the fraction depends on the currently selected fraction display format setting (improper fraction or mixed fraction). • You cannot switch from decimal format to mixed fraction format if the total number of digits used in the mixed fraction (including integer, numerator, denominator, and separator symbols) is greater than 10. • For details about the f key, see “Using S-D Transformation”.

Math e+1 Example 2: To input 1 + ' 2+3 MATH Math 1+!2 Math e+3 Example 3: To input (1 + 2 2 ) ×2= 5 MATH Math (1+'2c5e) w*2= • When you press = and obtain a calculation result using Math format, part of the expression you input can be cut off as shown in the Example 3 screen shot. If you need to view the entire input expression again, press A and then press e.

Sexagesimal Calculations • Performing the following types of sexagesimal calculations produces a sexagesimal result. - Addition or subtraction of two sexagesimal values - Multiplication or division of a sexagesimal value and a decimal value Appendix <#012> 2°20´30˝ + 39´30˝ = 3°00´00˝ Converting Values between Sexagesimal and Decimal Pressing e while a calculation result is displayed toggles the value between sexagesimal and decimal. Appendix <#013> Convert 2.255 to its sexagesimal equivalent. If you have a Casio fx-83ES that is no longer working, you can first try replacing the AAA battery. If that doesn't solve the problem, then you can consider replacing the calculator with a modern equivalent.

Calculation Examples Using Independent Memory • If the “M” indicator is on the display, perform the procedure under “Clearing Independent Memory” before performing this example. Example: 23 + 9 = 32 23+9m 53 – 6 = 47 53-6m –)45 × 2 = 90 45*21m(M–) 99 ÷ 3 = 33 99/3m (Total) 22 tm(M) Clearing Independent Memory Press01t(STO)m. This clears independent memory and causes the “M” indicator to disappear from the display. Math format causes fractions, irrational numbers, and other expressions to be displayed as they are written on paper. • Linear format causes fractions and other expressions to be displayed in a single line.Important! • For a very complex calculation or some other type of calculation that takes a long time to execute, the display may show only the above indicators (without any value) while it performs the calculation internally. About this Manual • The MATH mark indicates an example that uses Math format, while the LINE mark indicates Linear format. For details about input/output formats, see “Specifying the Input/Output Format”. • Keycap markings indicate what a key inputs or what function it performs. Example: 1, 2, +, -, !, A, etc. • Pressing the 1 or S key followed by a second key performs the alternate function of the second key. The alternate function is indicated by the text printed above the key. dddY s Overwrite Mode: c60) dddd s Inserting Input into a Calculation Always use the insert mode for this operation. Use d or e to move the cursor to the location where you want to insert new input, and then input what you want. k Displaying the Location of an Error If an error message (like “Math ERROR” or “Syntax ERROR”) appears when you press =, press d or e. This will display the part of the calculation where the error occurred, with the cursor positioned at the error location. Specifying the Fraction Display Format To specify this fraction display format: Perform this key operation: Mixed 1Nc1(ab/c) Improper 1Nc2(d/c) Specifying the Statistical Display Format Use the following procedure to turn display of the frequency (FREQ) column of the STAT Mode STAT editor screen on or off.
